Chromosomal Aberration of the 11q23 Locus in Acute Leukemia and Frequency of MLL Gene Translocation Results in 378 Adult Patients

Abstract excerpt

Structural abnormality of the 11q23 band (11q23+) bearing the MLL gene translocation (MLL+) is a recurrent chromosome change observed in 3% to 7% of acute lymphoblastic leukemias and in 3% to 4% of acute myeloblastic leukemias. The resolution of conventional cytogenetics (CC) in detecting 11q23 rearrangement is limited when the translocative partner has a telomeric location; furthermore, CC can barely...
